Amazon has a few sets on discount worth noting. Despite these reductions, I get the feeling everyone's just waiting on the fall stuff to arrive. Still, now would be a good time to fill in those holes in your collection before they get discontinued and skyrocket in price in the aftermarket. Besides everyone needs more Ewoks:

And don't forget, you can pre-order the LEGO Batman: Visual Dictionary from DK Publishing for the low, low price of $13.75. Authored by Daniel Lipkowitz, the book features the previously announced Electro Suit Batman exclusive minifig. The publication date is set for September 17, 2012. Pre-order it today:

Be careful this is Amazon trickery going on (sort of) - the discounts aren't quite as good as they look - check the prices on lego.com versus the "list price" on Amazon, and you see the discounts on Ewok Attack 7956 (MSRP$24.99) and Geonosian Starfighter 7959 (MSRP$29.99) are based on a higher list price than the MSRP. The Batwing Battle Over Gotham City 6863 price does match Lego.com. From Amazon you will usually save on tax and shipping if you buy enough, so there are good discounts to be had, but just be aware that the "List Price" is not the MSRP.

(I've had this issue with product other than Lego from Amazon, particularly when the product goes out of stock from Amazon and is listed through a linked seller - the 'list price' can jump by 50% or more and subsequent discounts are still a rip-off compared to the real MSRP...aftermarket is a whole other issue)
